Large Tesla's Lamp Plasma Ball

The Large Tesla’s Lamp Plasma Ball is a hands-on demonstration of electrical discharge, inspired by early high-voltage experiments. Inside the glass sphere, a mixture of noble gases—including neon, argon, and xenon—reacts to a high-frequency alternating current electrode, producing glowing filaments that move and respond to touch. The larger globe size makes the electrical patterns more visible and dynamic, making it an engaging addition to desks, classrooms, or science-focused displays.
